At one time I was focused on the amazon associate program. One of the reasons why I am moving away from amazon is because it lacks the ability to create customized rss feeds. Amazon can create feeds, but not as good as Ebay.
Amazon is ok, but it needs to take an example from ebay. I can create a store front in amazon, embed it into my site and its takes several seconds to load.
The single banners are good, I like to use them in articles or around videos.
